Old NAB scripts won't run with v0.7

Hi Henri,

Is the source documentation on the NAB site up-to-date with the new version 
of NAB?  I ask because the simulation scripts I used to run on v0.6-1 no 
longer work on v0.7 (numerous lines incrementally return errors).  Maybe I'm 
missing something but I've checked the problems against the source 
documentation and I can see no reason why I'm getting these errors.

For example, when I execute:

Script_utils.init_greedy_world();;

I get the error message:

Unbound value Script_utils.init_greedy_world


Many Thanks,

Dan Madadi
